How to get into the solar energy field?

We Answered:

You don't need to go back to college, unless you want to become an engineer working on designing new solar systems. I would look for local solar installers and talk to them. If you live in the southwest US, California, New Jersey, Japan, Germany or Spain you might have a better chance because these are the largest markets for solar power.

I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills. It was written by a Renewable energy enthusiasts Michael Harvey the diy called Earth4energy. You can get your copy to save energy and help environment while eliminating your power bills.

How is Solar Energy transformed into electricity?

We Answered:

It works like a semiconductor where sunlight knocks electrons loose and creates holes. This creates an electrical current in the semiconductor. You might want to review photovoltaics and semiconductors to understand solar cells.

OR and alternative but plausible answer

solar energy is transferred into heat, especially air. If you have a large greenhouse tower (like a tower made of glass) with an open top, the air inside will heat up and it will rise to the top and out where the cooler air is. If a turbine (like a windmill) is placed at the top end, the air will spin the turbine to create electricity.

How is solar energy transformed into electricity?

We Answered:

They use what's called a photodiode. It's a semiconductor made mostly from silicon. photons from the sun strike the material and excite the electrons in it.

the electron is moved from a valence energy level, (where it takes part in bonding the material together) to a level where it breaks free of the valence and is allowed to flow freely.

The electron flows through the material, and the hole it left behind is filled with an electron form the atom next to it, thus the hole flows in the opposite direction and is filled in at the outer most extremity by a free roaming electron from space.

In this way an electrical current flows through the material.

How solar energy in converted into electricity and stored? what is that electrons or chips and batteries?

We Answered:

Solar or light can be converted into current and batteries can be made at a smaller scale. Example is, small calculators are powered by solar cells.

As for as construction of those batteries they are made of smaller cells and then smaller cells are joint with other smaller cells to make little large cells. Its very expensive to make them on commercial level thats why we are addicted to oil.

Cheap things sometimes don't come cheap.
